  1. 1. The Role of Functional Traits and Trade-offs in Seasonal Succession of Phytoplankton Community Structuring : A numerical investigation of resource acquisition traits of Lake Constance

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Ayesha Nagahage; [2024]
    Nyckelord :Phytoplankton; resource acquisition; traits; trade-off; resource limitation;

    Sammanfattning : Long-term ecological research in deep lakes offers valuable insights into understanding changes in trophic states and organization of phytoplankton assemblages. Utilizing five decades of phytoplankton taxonomic trait data from pre-alpine Lake Constance, a confirmed negative relationship was found between phosphate and light affinity at the annual community trait level.

  3. 2. Biopolymers processed and used as enzyme carriers

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Dániel Mészáros; [2023]
    Nyckelord :Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

    Sammanfattning : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. LÄS MER

  4. 3. Utmattning av implantat-förankrade bro-konstruktionermed ett frihängande led och två olika fixturdiametrar. En pilotstudie

    Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

    Författare :Ahmed Yassin; Mohammed Al-Haideri; [2023]
    Nyckelord :Cantilever; Dental implants; Fixed dental prosthesis; Fatigue; Fracture strength; Implant angulation; Brotthållfasthet; Dentala implantat; Fast protetik; Frihängande led; Implantatvinkling; Utmattning.;

    Sammanfattning : Purpose: The purpose of this study is to evaluate how implant-supported fixed dental prosthesis (FDP) restorations with a cantilever at abutment level resist fatigue by dynamic loading and thermocycling depending on the fixture diameters.   Material and method: The study involved two groups with three specimens in each group, based on the diameter of the fixture, 3.

  5. 4. Photovoltaic hosting capacity study for a residential area in Uppsala using a synthetic low voltage network

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Ikenna Mbah; [2023]
    Nyckelord :Hosting capacity; performance index; low voltage network;

    Sammanfattning : With the growing acceptance of photovoltaic (PV) systems globally including Sweden, an increasing number of PV systems has continually been installed all through Sweden. In this study, a selected residential area in Uppsala Sweden is considered as a possible site for PV system installation. LÄS MER

  7. 5. Autonomous Quadcopter Landing with Visual Platform Localization

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Martin Blaszczyk; [2023]
    Nyckelord :UAV; Autonomy; Landing; Fiducial markers; QR; QR-code; Drone; Platform; MPC; UAV control;

    Sammanfattning : Multicopters such as quadcopters are a popular tool within industries such as mining, shipping and surveillance where a high level of autonomy can save time, increase efficiency and most importantly provide safety. While Unmanned Aerial Vehicles have been a big area in research and used in the mentioned industries, the level of autonomy is still low. LÄS MER
